摘要 |
A structure configured to disconnect circuit elements. The structure generally includes a dielectric layer over a light-absorbing structure, and a lens over the dielectric layer and the light-absorbing structure, configured to at least partially focus light onto the light-absorbing structure. The light-absorbing structure absorbs a first wavelength of light with a minimum threshold efficiency, the lens is substantially opaque to the first wavelength of light, and the dielectric layer is substantially transparent to the first wavelength of light. The structure advantageously provides improved reliability and smaller chip area, thereby increasing the yield of the manufacturing process and the numbers of die per wafer (both gross and good).
